Question

Find the p-value as a range using Appendix D. (Round your left-tailed test answers to 3 decimal places and other values to 2 decimal places.)

		p-value
(a) Right-tailed test	t = 1.457, d.f. = 14	between  and
(b) Two-tailed test	t = 2.601, d.f. = 8	between  and
(c) Left-tailed test	t = -1.847, d.f. = 22	between  and

Answer 1

P value using t score and degree of freedom is calculated using t table shown below as:

a) If it is right tailed test and t=1.457 and Degree of freedom=14 then p value:

0.05<P value<0.10

And the exact p value is 0.0834

b) If two tailed test and t= 2.601 and df=8 then p value:

0.02<P value< 0.05

And the exact p value is 0.0316

c) If it is left tailed test and t=-1.847 and df=22 then p value:

0.02< P value <0.05

And the exact p value is 0.0391
